3 EventRequests: 100, 1,000, and

10,000 Parameters

•

1 and 2 DCPConsumers

•

Measured various frequencies

Pentium M 1.4Ghz with 1 GB RAM

•

Windows XP Pro

–

Interface A Tests

• 3 Test Scenarios:

– Interface A only: Create Data Collection Report, but no

XML Serialization/Deserialization

– Full XML Serialization/Deserialization – sending to 1 or

2 DCPConsumers

• DCPConsumers do nothing with the data

– Full XML Serialization/Deserialization – sending to 1 or

more DCPConsumers

• DCPConsumers write data to a text file

• Data Types:

– String (25%), U/I1-8 (50%), F4/F8 (25%)

• No optimization techniques were used in these tests

• Performance improvements are highest in your data

gathering implementation

– Analyze performance trade-offs for consolidated versus

distributed systems

– Data collection and synchronization is critical

• In-house Interface A development

– If using .NET, learn C# or VB

– Learn Web Service Development
